Electric vehicle owners in some states are paying higher annual fees for driving zero-emissions cars than their gas-guzzling friends, according to new analysisby Consumer Reports.

Of the 26 states that impose fees on electric vehicles, 11 charge more for an EV than an owner of a traditional gas-powered car ends up paying in gasoline taxes every year. Three of those 11 states charge more than twice the amount.

Trends for the fees, generally paid through annual registration renewals, don’t look promising either. Another 12 states are considering their own EV fee proposals — seven of which would double over time.
